ABSTRACT
Abstract

Objective:

The objective of PHASE-MX registry is to validate the efficacy and safety of the pharmacoinvasive strategy in comparison with percutaneous coronary intervention (PCI) in patients with acute myocardial infarction with ST segment elevation (STEMI) in a metropolitan region of Mexico. The primary outcome will consist of the composite of cardiovascular death, re-infarction, stroke and cardiogenic shock.

Methods:

The PHASE-MX registry will include a prospective cohort of patients with STEMI who received reperfusion treatment (mechanical of pharmacological) in the first 12 h after the onset of symptoms. The registry is designed to compare the efficacy and safety of primary PCI and pharmacoinvasive strategy. The simple size was calculated in 344 patients divided into two groups, with an estimated loss rate of 10%. Patients included in the PHASE-MX cohort will be followed for up to one year.

Conclusion:

In Mexico, only 5 out of 10 patients with STEMI have access to reperfusion therapy. Pharmacoinvasive strategy is takes advantage of the accessibility of fibrinolysis and the effectiveness of PCI. The present research protocol aims to provide information that serves as a link between information derived from controlled clinical trials and records derived from real world experience.
RESUMEN
Resumen

Objetivo:

El objetivo del registro PHASE-MX es validar la eficacia y seguridad de la estrategia farmacoinvasiva en comparación con la angioplastia coronaria transluminal percutánea primaria (ACTPp) en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en una región metropolitana de México. El desenlace primario es el compuesto de muerte cardiovascular, reinfarto, accidente vascular cerebral y choque cardiogénico.

Métodos:

El registro PHASE-MX es una cohorte prospectiva de pacientes con IAMCEST que recibieron tratamiento de reperfusión (mecánico o farmacológico) en las primeras 12 horas desde el inicio de los síntomas, atendidos en el Instituto Nacional de Cardiología Ignacio Chávez. El análisis estadístico se basa en la no inferioridad de la estrategia farmacoinvasiva en comparación con la ACTPp. Se calcula un tamaño de muestra de 344 pacientes divididos en dos grupos (angioplastia primaria y estrategia farmacoinvasiva), considerada una tasa de pérdidas de 10%. Los pacientes incluidos en la cohorte PHASE-MX se seguirán durante un año.

Discusión:

En México, sólo 5 de cada 10 pacientes con IAMCEST tienen acceso al tratamiento de reperfusión. La estrategia farmacoinvasiva aprovecha la accesibilidad de la fibrinólisis y la efectividad de la ACTPp, por lo que podría resultar el método de elección en el tratamiento del IAMCEST en la mayoría de los casos. El presente protocolo de investigación pretende aportar información que sirva como enlace entre la información derivada de los estudios clínicos controlados y los registros derivados de la experiencia del mundo real.
